ELECTRICAL CONNECTER.

Application led Uctober 1, 1920. Serial No. 418,992.

'a specification.

My invention'relates to an electrical connecter intended more particularly to be used 4for making temporary and emergency connections to duplex wire for the operation of lamps, portable electric tools, etc. Such wire or conductoris ordinarily used in temporary wiring of ships u/nder construction as well as new buildings; and the connecter embodying my invention is intended for application -to wiring of this temporary character. Speaking in general terms, my .connecter consists ofa device capable of being readily a plied to the wire or cable and to cut throug theinsulation by knife contacts with' only a slight abrasione or alteration of the insulation and without injury to the copper wire conductors. The vari# ous features of advantage and utility in my connecter will be apparent vfrom the description hereinafter given.

In the drawing Fig. 1 is a side elevation of my connecter with the various means thereof shown thrown to o en position and ith the conductor or cab e shown in seci tron; Fig. 2 is an elevation of my connec- -ter shown in closed' position and applied to the cable; Fig. 3 is an end elevation of the conductor with a portion broken` away; Fig. 4 is a section on the line 4--4 of Fig. 25 Fig. 5 is a section on the line V5--5 of Fig.. 3; Fig. 6 is a detail of one of the discs pivotally connecting the two'main members of the connecter, and Fig. 7 is a detailed view of the pivoted portions of such members.

Referring to the particular embodiment of my invention asl erein shown, my connecter includes two main ortions or blocks 1 and 2v which are pivote upon each other towards their lower` ends in simple manner, and which are made of suitable insulating material. In the present instance the pivotal connection between these two blocks is obtained by the two circular discs 3 which have inturned flanges 4 adapted to engage in the circular ooves 5 at the bottom of the circular soc ets 6 formed on opposite sides of the two blocks, each block bearing one-half of the sockets and grooves. These two discs are held iny place by means of the transverse screw 7 en aging both of the discs and thereby holding them in connection with said blocks.

The blocks areprovided on their inner adjacent sides with registering slots 8 forming a transverse opening to receive the cable 9 which is provided with the two cop er wires or conductors 10 and l1, placed 81de by side but separated a short distance and surrounded by insulation in the usual way as illustrated in Figs. 1 and 4c. The blocks Aare also provided with top longitudinal slots 12 registering with each other and communicating at their inner ends with the slots 8 by means of vertical slots 13. yThe block l is also provided on its inner face with a slot or recess 14 triangular in section and running upwardly to communicate with the slot 8.of such block. The vblock 2 is provided on its inner face with a triangular shaped projection 15 ada ted to lit in the slot or -recess Maand to fibrin with its u per edge a support for the cable when t e locks are in closed position and appliedv to the cable. v

The lower ends of thefblocks are vided on oI posite sides with suitable atea serving. to old'the blocks in position in addition to the pivoting means, and also to limit the pivotal movement or swing of the blocks. These plates 16 are similar but oppositely arrangpd, and in the present instance they are oth secured to the member 1 by means of the screw 17. They are of a shape to iit upon the side of the lower rojectingqportions 18-and 19 of the mem ers 1 and .2 and the same are inset into the sides of such members or blocks. In addition the block 2 is recessed upwardly to the inclined line 20 above the edge of the ri ht hand half of the late 16, as shown in ig. 2. As a result t e contact of the upper end 20 of the recess in the block 2 against the top edge of the plate 16 limits the swinging nliovement of the blocks, as shown 1n Two opposed knife contacts 21 are. arranged-in the inner ends of the slots or recesses 8 in position to enga-ge the cable and cut through the insulation to the conductin wires when the blocks are brought an clamped together, as shown in Fig. 2. Each knife contact has a screw threaded stem 22 screwing into the base of a holder 23 for holding a fuse 24. This fuse is held yieldin l at its lower end by a simllar fuse holder 25 which holder in turn is connected with the connecter 26 for the wires 27-27 runnin to the lamps or electric tools, or other ace or instrument of use. The fuses and t eir holders are arran ed in slots 28 in the outer sides of the bloc s 1 and 2 and the same are held closed on such sides by means of the pivoted plates 29, p ivoted .at their upper ends 30 and each havmg at its lower end a spring lip 31 ada ted to engage under the shoulder 32 of its b ock.

A clamping bolt 33 ispivoted tothe block 1 on the pin 34. This bolt is received within the to slots 12 and is provided at its outer en with a thumb nut 35 -having a collar or washer 36 which is here inte al with the nut and adapted to bear against the outer side of the block 2 when in a clampinposition, as shown in Fi s. 2 and 5.

Descrl mg the application of t e connecter to a cable, the locks 1 and 2 and the clamping bolt are opened'to the position shown in Fig. 1 and inserted u on the cable 9 as shown therein; The bloc s are thereupon swung closed and the clamping bolt is swung to operative position and the thumb nut tlghtenedA whereupon the knife contacts bite into the insulation and come into contact with cable wires 10 and 11 thereby making connection with such cable. At this time the cable is supported u on the top of the projections 15,y and is hel lfrom bul ing upwardly by means of the downward y rejecting portion 37 of the clamping bolt. gfhe extreme lower portion is preferably a block of insulating material.
